It probably doesn't matter that much but I prefer doing it gradually in a pot and all at once when it's in the ground.
If you pay attention to where the auxiliary meristems start to form on rhizome that information can be very useful.
Here's an example of double ratooning, a variegated mother plant growing in the ground produces a beautiful offshoot. Once that offshoot passes the stage of starting to form it's own auxiliary meristems is when I would raise the soil level. This will move the apical meristem in the offshoot, once it's far enough away to safely remove I'll separate it above where it's auxiliary meristems are. Because it's auxiliary meristems are still connected to the main mother plant their growth rate is going to be amazing. They are going to grow so fast that their plant tissue is going to be noticeably less dense.

Waiting for the roots is the safest way because it's the first indicator of where the meristem is.
